36 VISIONEER STROBE XP 450 SCANNER INSTALLATION GUIDE

ADJUSTING COLOR AND GRAY IMAGES

The Scan Manager has three buttons—Descreen, Sharpen, and Auto

Level—for adjusting color and gray images. These buttons are available

when the 24-Bit Color or 8-bit Gray Image Types are selected.

DESCREEN IMAGE

Select this option when scanning a picture from a newspaper or

magazine article, sales catalog, or other source that contains images with

patterns or dots. Scans of patterns or dots sometimes have a distorted or

wavy appearance. The scanner scans the item to compensate for the

patterns and dots, and produces a clearer image. The scanning may slow

down a bit when this option is selected. You don’t need to select this

option when scanning photographs.
